It was great to experience an ayahuasca center run directly by an indigenous Peruvian who is also passionate about organic farming and medicinal plants beyond ayahuasca. The ayahuasca brew at the center is very good, as are the freshly extracted other medicinal juices provided at the center.
However, this is probably not the best place for people with asthma/bronchial conditions. Not only do the two shamans and two facilitators constantly smoke mapacho (jungle tobacco 12 times stronger than regular cigarettes) throughout the ceremonies, they encourage participants to smoke as well, and leave a bag of mapacho and lighters inside the ceremonial hut. I found it hard to breathe at times, and came down with a terrible cough from all the smoke exposure.
Also, vomiting is highly encouraged at this center, and other forms of purging (crying, yawning, burping, etc.) are not given discussion or importance, though oftentimes its crying that is most healing for people, especially men.
